Description
Technical field
The present invention relates to technical fields of mechanical processing, and in particular to the survey of involute internal spline gear shape minute angle offset
Amount.
Background technique
In the product comprising involute inner spline structure, often there is involute internal spline gear shape small to reference center's line
The requirement of angle (2 ° of <) offset.After involute inner spline processing, key characteristic must be subject to measurement and control.However, conventional
Method can not directly measure to obtain involute internal spline gear shape to reference center's line minute angle offset, cause to try in new product
Stage processed, the parameter can not be controlled.When mass production, product defects are especially prominent.
Summary of the invention
The object of the present invention is to provide a kind of methods of involute internal spline gear shape minute angle offset measurement, existing to solve
There is the problem of technology.
To realize the present invention purpose and the technical solution adopted is that a kind of such, involute internal spline gear shape minute angle
The measurement method of offset, comprising the following steps:
1) two parts to be measured are stacked together.Wherein, there is part internal spline and part base on the part to be measured
Quasi- hole.
2) the part internal spline that two parts to be measured are sequentially passed through using splined mandrel, the position of two parts to be measured is consolidated
It is fixed.The part internal spline of described two parts to be measured is overlapped, the part datum hole appearance position difference of two parts to be measured.Its
In, external splines identical with part internal spline parameter is provided on the outer wall of the splined mandrel.
3) the part datum hole public domain inner wall value BB ' of two parts to be measured is measured.
Further, also have after step 3) and pass through public domain inner wall value BB ' calculating involute inner spline minute angle
The correlation step of offset б.
The solution have the advantages that unquestionable:
A. reviewer, which can be convenient, fast measures and determines whether involute internal spline gear shape minute angle offset is full
Sufficient product design requirement, achievees the purpose that control important parameter characteristic；
B. the quality of batch detection part key characteristic can be realized.
Detailed description of the invention
Fig. 1 is design of part schematic diagram to be measured；
Fig. 2 is splined mandrel structural schematic diagram；
Fig. 3 is operation schematic diagram；

In figure: splined mandrel 3, external splines 301, part to be measured 4, part internal spline 401, part datum hole 402.
Specific embodiment
Below with reference to embodiment, the invention will be further described, but should not be construed the above-mentioned subject area of the present invention only
It is limited to following embodiments.Without departing from the idea case in the present invention described above, according to ordinary skill knowledge and used
With means, various replacements and change are made, should all include within the scope of the present invention.
Embodiment 1:
Referring to Fig. 1, there is part internal spline 401 and part datum hole 402 on part 4 to be measured.Referring to fig. 2, splined mandrel 3
Outer wall on be provided with external splines 301 identical with 401 parameter of part internal spline.
The center of circle of the corresponding reference circle of the part internal spline 401 of part 4 to be measured is O1, the circle of the corresponding circle of part datum hole 402
The heart is O2.With O1O2Line is benchmark center line.Part 4 to be measured is opposite for 401 involute internal spline gear shape of part internal spline
The minute angle offset of reference center's line has strict demand.In the design scheme of part 4 to be measured, spline tooth top a relative to
Reference center line O1O2Angle offset be 1.41 °, i.e. straight line O1O2With straight line O1Design angle between a is 1.41 °.However,
In actual production, involute spline will appear offset relative to nominal size position.Conventional method can not directly measure to obtain
Involute internal spline gear shape causes the parameter in the trial production of new products stage that can not be subject to reference center's line minute angle offset
Control.
The design feature of the present embodiment part 4 to be measured by analysis, converts linear measure longimetry problem for angle measurement problem.
Referring to Fig. 1, chooses part datum hole 402 and correspond to round one perpendicular to straight line O1O2Diameter, the diameter and straight line O1The friendship of a
Point is b.According to triangle relation and the design feature of part it is found that the offset of spline tooth top a angle is different, the position of b point
It can be with variation.The minute angle offset of involute internal spline gear shape relative datum center line can be anti-by the offset of b point
It reflects.
The present embodiment discloses a kind of measurement method of involute internal spline gear shape minute angle offset, including following step
It is rapid:
1) two parts 4 to be measured are stacked together.In the present embodiment, two parts 4 to be measured are respectively labeled as zero
Part A and part B.The center mark of the corresponding reference circle of the part internal spline 401 of part A is O1, the corresponding circle of part datum hole 402
Center mark is O2, spline tooth top mark is denoted as a.The center mark of the corresponding reference circle of the part internal spline 401 of part B is O1', zero
The center mark of the corresponding circle of part datum hole 402 is O2', spline tooth top mark is denoted as a '.
2) referring to Fig. 3, the part internal spline 401 of part A and part B are sequentially passed through using splined mandrel 3, by part A and
The position of part B is fixed.At this point, the reference circle of external splines 301 and part internal spline 401 is overlapped.The tooth of the external splines 3011
The wide flank profil cut-grafting with part internal spline 401 cooperates.The part internal spline 401 of the part A and part B is overlapped.The part
The part datum hole 402 of A and part B due to 401 tooth form minute angle of part internal spline offset and change in location occurs.Part
The corresponding circle intersection of the part datum hole 402 of A and part B.
3) 402 public domain inner wall value BB ' of part datum hole is measured using miking.
The part datum hole 402 for choosing part A corresponds to round one perpendicular to straight line O1O2Diameter.It is straight where the diameter
Line circle corresponding with the part datum hole 402 of part A and part B intersects at B and B ' respectively.Referring to fig. 4, BB '=benchmark bore dia-
2×O2O2', O2O2'=O1O2×tanб.Wherein б is the little deviation angle value of angle, and б value is different, then O2O2' value is just different,
Corresponding public domain inner wall value BB ' value is just also different.Angu-lar deviation is bigger, O2O2' spacing it is bigger, benchmark nose end
Public domain inner wall value BB ' is then shorter.Therefore, the indirect measurement angle of length of measurement public domain inner wall value BB ' can be passed through
The variation of little deviation.
4) compare public domain inner wall value BB ' and BB 'minAnd BB 'max.If BB 'min≤ BB′≤BB′max, then involute
Internal spline minute angle deviation is qualified, on the contrary then unqualified.Wherein, BB 'minIt is the permission minimum value of BB ' value, i.e., angle is permitting
BB ' respective value when taking extreme value in deviation range perhaps.BB′maxIt is then the permission maximum value of BB ' value, (O when zero deflection2、 O2' two o'clock
Be overlapped) BB ' respective value, i.e. benchmark bore dia.
5) in actual production, public domain inner wall value BB ' calculating involute inner spline minute angle can be passed through as needed
Offset б.
The present embodiment is easy to implement, realizes immeasurability, is difficult to measure measurable leap.
